Preheat your deep fryer to 375 degrees.
Set up a standard breading station by pouring the flour into one bowl, the eggs into a second and the breadcrumbs and oregano into a third.
To keep your hands from becoming breaded use one to handle the sticks while they are dry and the other hand while they are wet. Dredge the mozzarella sticks in the flour first then shake off any excess before adding to the egg. Coat well with the egg, drain well then toss into the breadcrumbs. Coat well then let rest. It is best to bread all the sticks once than go back and bread them all again and then a third time. A few minutes rest in between coats will help the bread crumbs adhere.
Fry until golden brown and crispy.
